7 Claims. (CI. 20-565) The present invention relates to a novel window structure, and more particularly to a window structure of the type having a plurality of sashes mounted for pivotal movement.

One problem encountered when .using windows having pivotally mounted sashes is that of providing air and weather proof joints between adjacent sashes and between the sashes of the window frame. While certain prior art devices have been adequate in some respects, they have not been entirely satisfactory. It is, therefore, an object of the present invention to provide a novel window structure'of the above described general type, wherein the joints between adjacent sashes and the sashes in the window frame are positively sealed to insure air and weather tightness.

Another object of the present invention is to provide a novel window structure of the above described type with novel means for lockingthe sashes in their closed position.

A more specific object .of .the present invention is to provide a Window structure with novel means which locks the sashes in their closed position and also seals the joints between the sashes and between the sashes and the window frame.

Still another object of the present invention is ,to provide a novel window of simple -structure, .wherein glass window panes are removably retained in the sashes by elements also forming part of the sealing and locking means.

Other objects and advantages of the present invention will become apparent from the followi g d scription and theaccompanying drawings, wherein:

Referring nown ore specifically to the drawings, wherein like parts are designated by the same nu nerals throughout; the various figures, a window structure 10 embodying theiprinciples of this invention is shown in Fig. l. flhe twindowtstructure includes a fre ne having upper andlower horizontal members 12 and 14 and vertical side rneir bers 16 and 18. These fr ame nembers may be formed of any suitable material, such as steel, aluminum, er plastic. Preferably, the frame members are elongated ,channels with a generallyiI- shaped transverse cross section nd are disposed so that the open-en d of the U faces inwardly of the ra A plurali y o s she -29 .22 aad26a pivotallv m un e within he y .rneians fully 1 be h Q I bQQ a h fi o t PE E'PQSQ e illu t tion the window structure10 hasbeenshown as including "ice four sashes mounted for pivotal movement about horizontal axes, it will be obvious from the following description that the principles of this invention might be applied to window structures having any number of sashes, which sashes might be mounted for pivotal movement about either horizontal or vertical taxes.

Since all the sashes are substantially identical, only sash 22 will be described in detail. As shown in Figs. 1 and 2, the sash 22 includes a rectangular frame having upper and lower members 28 and 39, respectively, and vertical side members 32 and 34. These sash frame members are preferably constructed from a heat insulating material, such as plastic or wood. Preferably, the sash frame members are recessed on opposite sides thereof, as at 36 and 38 (see Fig. 2) in order to receive and hold a pair of window panes .44} and 42 in parallel spaced apart rela* tionship. Sealing gaskets and 46 are positioned against the vertical surfaces of the recesses 36 and 38, respectively, and the Window panes 4Q and42 are clamped against these gaskets by means of plate members secured to the 'sash frame. As shown best in Fig. 2, the outer window pane 4a is clamped against the upper sash member 23 by a clamping plate 43, which clamping plate is secured to the sash by a plurality of screws 5%). The inner glass 42 is similarly clamped against the upper sash member by a plate 52. The lower edgesof the window .panes 4t) and 42 are clamped to the lower sash member by plates 54 and 56, respectively. Asshown in Fig. 5, ends of the window panes {i0 and ilare clamped to the end sash member 34 by identical cover plates 53 andtit it is understood, of course, that the opposite ends of the window panes are clamped against the sash member 32 by cover plate men bets similar tomembers 5 8 and 6b. In order to insure that the outer window pane as is sealed against entry of moisture or ai a sealing gasket ;62 .(see Fig. 2) is positioned betweenthe cover plate members and the glass, and the ends of the vertical and horizontal cover plate members overlap each other and are securedto the window sash by commonscrews 65! and 66, as illustrated in Fig. 6.

Each of the window sashes is pivotally supported within the window frame by pivot pins at opposite sides of the window frame. Preferably,the common axis of each pair of pivot pins coincides with the horizontal center line of their associated sash. The pivotal supporting structure,

which is identical at both sides of each sash, is best illustrated in Fig. 5 and includes a pivot pin 68 slidably extending through a suitable aperture in the U-shaped window frame member for entry into an aperture in .thevertical sash frame member. A cotter pin it! is secured to the pivot pin to prevent complete removal of the pivot pin from the U-shaped frame member. In order to insure assembly of the pivot pin within the aperture in thesash, a plate member 72 is fixed to the pivot pin, and a compression spring 74 acts .between the plate member 72 andthe U-shaped frame member for urging the pivot pin intoen- V gagement with thesash. With this structure, the sash may be removed if desired merely by pressing the plate member 72 against the action of the spring, wh.ereby the pivot pin is withdrawn from the sash. In addition, the plate memberlZ extends for and coincides with the entire vertical height of the window sash, and a resilient sealing pad 76 overlies and coincides with the plate member for engagement with the sash. With this structure, it is seen that the spring acting on the plate 72 not only maintains the pivot pin in engagement with the sash, but also urges the resilient sealing pad 76 into positive sealing engagement with the sash. i

In accordance with ,a feature of this invention, novel means is provided for insuring an air and weather tight seal at the junction between marginal horizontal edge portions of adjacent sashes and between adjacent horizontal edge portions of the upper andlower sashes and the window frame. This novel means is illustrated best in Fig. 2 and includes a resilient elongated sealing member 73 which is mounted on and extends along the entire upper surface of the upper frame member 28 of each sash. A complementary sealing member St which is constructed of any suitable relatively hard material, is slidably mounted for vertical movement in a suitable slot in each lower sash frame member 30. The member 80 is actuated by cam means disposed adjacent opposite ends thereof. This cam means is shown best in Figs. 2 and 6 and includes an eccentric cam 82 disposed in a suitable opening 84 in the member 89. The cam 82 is mounted on a shaft 86 journaled in the lower sash frame member and extending inwardly of the window. The inner end of the shaft 86 is provided with a handle 83 to facilitate operation thereof. With this structure, it is seen that upon rotation of the handle 88, the member 78 may be moved from a raised position downwardly into positive sealing engagement with the relatively soft member 73. The upper or ge of the member St) is continuously sealed with respect to the frame member 30 by an elongated strip of resilient sealing material 89 filling the portion of the slot in the frame member 3th above sealing member 80. While the cooperating elements '78 and 86 provide an air and weather tight seal, it is undesirable to permit moisture to enter the space between the sashes, and, therefore, the above described window pane clamping plate 54 is provided with an extension 90 which closes the gap between adjacent sashes and directs any moisture, such as rain water, directly to the surface of the adjacent sash.

Since the lower sash frame member 30 is preferably formed from wood or plastic, repeated operation of the cam means and shaft 86 may cause undesirable wear of the'sash member 30. In order to prevent such wearing of the sash member, the clamping plate member 56, which is preferably made from metal, such as stainless steel or aluminum, extends down and around the lower edge of the sash member 30 and provides a bearing for the shaft 86. In accordance with another feature of this invention, the cooperable members 78 and 80 not only provide a positive seal, but also serve to lock the window sashes in their closed positions. This locking action takes place when the member 80 is partially imbedded in the resilient member '78, as shown in Fig. 2, whereby marginal portions 92 and 9d of the resilient member interengage with opposite sides of the member 80. In order to prevent the marginal portions 92 and 94 of the resilient member from collapsing whenever a force is applied to the sashes tending to open them, the window pane clamping plates 48 and 52 are provided with upward extensions 96 and 98, respectively, of generally inverted U-shape, which U-shaped extensions engage opposite longitudinal edges of the resilient member 78, thereby preventing undesirable flattening or collapse of the resilient member.

The junction between the upper edge of the sash 20 and the upper horizontal window frame member 12 is sealed and locked by substantially the same means as the junctions between adjacent sashes. Thus, as shown in Fig. 3, an elongated block-like member 100 is mounted within the U-shaped frame member 12, and a sealing and locking member 80 is mounted in the member 100 in substantially the same manner as the sealing members 80 are mounted in the lower sash frame members 30. It will be noted that the front leg 102 of the U-shaped window frame member 12 preferably extends below the upper edge of the sash 2b in order to direct rain water and the like past the junction between the sash and the window frame member. in addition, a plate member 194 having a flange 1% engageable with the front leg 102 is provided for obtaining at least a partial seal and also for properly locating the window sash 20 in a substantially vertical closed position. The remainder of the locking and sealing structure for the junction between the sash 2t and the window frame member 12 is identical to that described above,

as shown by the application of identical numerals to iden tical parts.

The junction between the lower sash 26 and the lower window frame member 14 is sealed and locked by a structure substantially identical to that described above, except that the resilient member 78 is replaced by another resilient member 108 which is mounted in the U-shaped frame member 14. In addition, the lower edge of the window pane 40 in the sash 24 is clamped by a plate member flit) which is slightly different from the above described corresponding clamping plate 54 in that the plate 110 extends so as to provide a flange 112 overlying the front leg 114 of the U-shaped frame member 14. it will be understood that the flange 112, the portions 0 of the cover plates 54, and the depending leg 102 of the window frame member 12 all act to locate the window sashes in the vertical plane of the window frame when the sashes are in their fully closed positions.

in some instances, it is desirable to provide shade means for covering all or part of the window structure 19. Such means is shown in Fig. 2 and includes a shade 116 of pleated metal foil which is disposed between the window panes 4t) and 42. The lower edge of the shade is preferably secured to the sash frame member 30, and the upper edge of the shade is connected with a suitable chain or the like 118 which extends out of the window sash through a suitable passageway 12%] formed in the upper sash frame member 28. Thus, by adjusting the position of the chain 118, the shade 116 may be raised or lowered as desired.

From the above description, it is seen that the present invention has provided a novel and simple window structure, wherein combined means not only locks the various sashes in their closed positions, but also provides a positive air and weather tight seal between the sashes and other portions of the window structure. Furthermore, it is seen that in accordance with the present invention, certain elements not only clamp the window panes in the sashes, but also form elements of this sealing and locking means and act to locate the sashes properly in their closed positions.

While the preferred embodiment of the present invention has been shown and described herein, it is obvious that many structural details may be changed without departing from the spirit and scope of the appended claims.
